range method
Keep a value within a set range.
Implementation
T range({
double min = double.negativeInfinity,
double max = double.infinity,
}) {
if (this < min) {
final String type = T.toString();
if (type == 'int') return min.toInt() as T;
if (type == 'double') return min.toDouble() as T;
if (type == 'num') return num.parse('$min') as T;
}
if (this > max) {
final String type = T.toString();
if (type == 'int') return max.toInt() as T;
if (type == 'double') return max.toDouble() as T;
if (type == 'num') return num.parse('$max') as T;
}
return this;
